You can perform an object profile merge on two, three, or four object profiles. The non-surviving profiles are the profiles that are not retained after the merge. These profiles are also referred to as merged profiles. The surviving profile is retained after the merge. This profile is also referred to as the main profile. During an object profile merge, the source records in the non-surviving profiles are transferred to the surviving profile, and the non-surviving profiles are given a status of “Merged”. The SBR for the surviving object profile is recalculated based on the existing source records for that profile along with the newly merged source records. The EUID of the surviving profile is always retained. The information that is discarded during a merge is stored in the transaction table, making it possible to restore the profiles to their original EUIDs if they were merged in error. You can specify which profile to retain during a merge and you can select fields from the non-surviving source record to be retained in the surviving source record.
